Select the relevant literature on health care big data sharing in CIKI database from 2014 to 2020, use Citespace visual analysis software to show the changing characteristics of health care big data sharing by means of knowledge map from the aspects of research hotspots and trends and academic community, and sort out and analyze this topic. The results show that the topic heat and research trend of health care big data have maintained a stable rise in recent seven years, but no academic community has been formed. It mainly includes the application of health care big data sharing and the problems and countermeasures in the application process. It expounds the application connotation and scope of data sharing, finds that there are problems in information privacy security, legislative guarantee and ethics in the sharing process of health care big data, and puts forward personal suggestions to provide reference for the sharing research of health care big data.
